: ) actually a good rule I use is never buy/short a stock into an earnings report/update.. Its just pure gambling and you can do much better playing it after the fact with the volatility.
Unless I have a large buffer.. and yes, sometimes that rule hurts me.. Look at my cover of a short I did on EK yesterday.. made a quick .50 and was happy covering at 27.16.. welp- look at it today :) : )
Seriously tho- holding into these events is pure gambling.. dont let anyone tell you otherwise
